These are obtained from the general expressions given in Eqs. (REF ) and (REF ), taking \((\alpha _1,\alpha _2)\) =\((\beta _1,\beta _2)\) , and assuming that the mixing matrix for the CP-odd Higgs bosons \(R_A\)  is parameterized by (REF ) with \(\gamma _2=\gamma _3\) =0.
The \(B_5\)  function is evaluated by using LoopTools [1]}.
We use the experimental values for the \(S\)  and \(T\)  parameters given in Ref. [2]}.
